What Are Application Security Testing (AST) Tools?

Application security testing tools are software solutions used to identify, analyze, and remediate security vulnerabilities in applications. These tools help developers and security professionals ensure that their applications are secure from potential threats and comply with security best practices. There are various types of AST tools, each with its own strengths and focus areas.

By using a combination of application security testing tools, developers and security teams can identify and remediate vulnerabilities in their applications, helping to minimize the risk of security breaches and data loss.

Why AST Tools Are Critical for Software Projects

Application Security Testing (AST) tools are critical for software projects because they help ensure that applications are secure, reliable, and compliant with industry standards and best practices. Integrating AST tools into the software development process can provide numerous benefits and minimize the risks associated with security vulnerabilities. Some reasons why AST tools are crucial for software projects include:

  • Early vulnerability detection: AST tools enable developers to identify and remediate security vulnerabilities during the development process, rather than after deployment. Early detection of vulnerabilities helps reduce the overall cost of fixing issues and minimizes the potential impact on end-users.
  • Improved security posture: By identifying and addressing security vulnerabilities, AST tools help improve the overall security posture of an application. A secure application is less likely to be compromised, protecting sensitive data and maintaining user trust.
  • Compliance with regulations and standards: Many industries have strict security requirements and regulations, such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), and the Payment Card Industry Data Security Standard (PCI DSS). AST tools help ensure that applications meet these standards, avoiding potential fines and legal issues.
  • Reduced the attack surface: AST tools help reduce an application’s attack surface by identifying and addressing potential security vulnerabilities during the development process. By minimizing the attack surface, you can decrease the likelihood of successful cyberattacks and protect sensitive data.
  • Facilitates DevSecOps: The integration of AST tools into the software development process supports the DevSecOps approach, where security is considered a shared responsibility throughout the development lifecycle. This approach helps create a culture of security and encourages collaboration between development, security, and operations teams.

Types of Application Security Testing Tools

Static Application Security Testing (SAST)

SAST tools analyze an application’s source code, bytecode, or binary code without actually executing it. These tools focus on identifying coding errors, security vulnerabilities, and other potential issues in the codebase itself. SAST is usually performed early in the software development lifecycle (SDLC), helping developers to identify and fix vulnerabilities before deployment.

Dynamic Application Security Testing (DAST)

DAST tools test the application during runtime, analyzing its behavior and interactions with other systems. By simulating real-world attacks, DAST identifies vulnerabilities that could be exploited by malicious actors. DAST is typically conducted during later stages of the SDLC and after deployment to ensure ongoing security.

Interactive Application Security Testing (IAST)

IAST tools combine aspects of both SAST and DAST, using a hybrid approach. They monitor an application during runtime while also analyzing its codebase. IAST tools provide developers with real-time feedback, enabling them to identify and remediate vulnerabilities quickly. IAST is often used in continuous integration and continuous deployment (CI/CD) environments.

Runtime Application Self-Protection (RASP)

RASP tools are integrated into an application’s runtime environment, monitoring and protecting it from attacks in real-time. RASP tools can detect and block malicious inputs, preventing the exploitation of vulnerabilities. They provide an additional layer of protection, helping ensure that even if a vulnerability is present, it is not exploited.

Mobile Application Security Testing (MAST)

MAST tools focus specifically on the security of mobile applications, considering the unique aspects of mobile platforms, such as Android and iOS. They combine various testing techniques, including SAST, DAST, and others, to identify vulnerabilities and security flaws in mobile apps. MAST tools also help developers ensure compliance with mobile security best practices and standards.

Software Composition Analysis (SCA)

SCA tools are used to identify and manage open-source components and third-party libraries used within an application. They help developers track the use of these components and identify potential security vulnerabilities, outdated components, and licensing issues. SCA tools enable developers to address risks associated with third-party dependencies and maintain a secure and up-to-date codebase.

How to Choose the Right AST Tools for Your Team

Here are some aspects to consider when choosing AST tools:

​​Know your applications and risk profile

To choose the right AST tools, you need to understand your applications’ architecture, dependencies, and criticality in terms of security. Identify high-risk applications that require more rigorous security testing and prioritize their needs. Additionally, consider whether your applications are web-based, mobile, or desktop, as this can influence which tools are most appropriate.

Align with your SDLC

The right AST tools should fit seamlessly into your SDLC and not disrupt existing workflows. Look for tools that can be integrated with your development environment, version control systems, and CI/CD pipelines. Ensure that the selected tools promote a collaborative approach to security, encouraging developers and security professionals to work together.

Evaluate tool accuracy and efficiency

When comparing AST tools, consider their accuracy in detecting vulnerabilities and the rate of false positives or negatives. High rates of false positives can create extra work for your team, while false negatives can leave your applications vulnerable. Choose tools with a good balance between accuracy and efficiency to minimize the impact on your team’s productivity.

Scalability and adaptability

As your organization grows or your applications evolve, you may require additional or different AST tools. Look for solutions that can scale with your needs and support multiple programming languages, frameworks, and platforms. Additionally, consider how quickly the tools can adapt to new threats and vulnerabilities in the ever-changing security landscape.

Vendor support and community

The quality of vendor support and the tool’s user community can significantly impact your team’s experience. Look for vendors with a reputation for responsive support and regular updates. A strong user community can provide valuable resources, such as tutorials, best practices, and troubleshooting tips.

Ease of deployment and management

Choose AST tools that are easy to deploy, configure, and manage. This can help reduce the burden on your team and ensure the tools are used effectively. Additionally, consider tools with centralized management and reporting capabilities, which can simplify the process of tracking and addressing vulnerabilities across multiple applications.

Continuous improvement

The right AST tools should promote continuous improvement in your team’s security practices. Look for tools that provide actionable insights and recommendations for addressing vulnerabilities, and that encourage developers to learn from their mistakes.

Budget considerations

While cost should not be the only factor when choosing AST tools, it is essential to find solutions that fit your organization’s budget. Consider both upfront and ongoing costs, including licensing, maintenance, and training.

Conclusion

In conclusion, AST tools are vital for modern software projects, helping teams identify and address vulnerabilities throughout the SDLC. By incorporating AST tools into the development process, organizations can create a proactive security culture, meet industry standards, and safeguard assets and user data in an increasingly competitive digital landscape.
